Abstract
The article describes the analysis of factors which restrict there liability of machines exploited by usage of staff lubricants. It also shows the possibility of forming a monomolecular layer of surface-active materials at the expense of chemisorption force as well as the layer’s influence on the physicochemical processes on the edge of phase separation. There are also the technologies of monomolecular protective film acquisition as well as of surface quality control presented in the article. The perspectives of using the mentioned technology during production and exploitation of machines are given.

Abstract

The object of study in the article is the efficiency of various methods to increase the load capacity of corrugated steel structures (CSS). Such methods as: increasing the thickness of the metal for the whole structure, extra reinforcement ribs and backfill ring reinforcement with fibre reinforced rebar considered. The efficiency evaluation based on structural design results using the finite element method (FEM) taking into account the economic indicators for considered methods.

The calculation results and efficiency indicators for each of the technical
solutions are given.
